Answer:
144
Step-by-step explanation:
It rotates out of 360 degrees, and since it is a pentagon that rotates from two of its vertices, then 360/5 would give us the amount it is rotating from one vertice. So 72. Then multiply it by two because you are moving from e to b.
144
To find the gradient you do change in y/change in x so...
-12 - 0
————- = -12/4 = -3
0 - - 4
Hope this helps! Any questions let me know :)
Answer:
All angles are equal because all sided are equal so the 1st 1 is 60 .
the 2nd is 80
Answer:
they are similar
Step-by-step explanation:
this is because of the degree of the angles and the measurements between the edges. The only reason it may not look the same is because it has been rotated and downsized.
The ar. of square =X^
=5.76
So,X=√5.76
=2.4
now, perimeter of square =4(X)
=4(2.4)
=9.6
So, the perimeter of the square is 9.6cm..
Thanks!
Hope it helps you..
